One of the things I found odd was that the Sensei doesn't allow for weight customization. This is something that I'm completely fine with, as the weight distribution of the Sensei is nicely centered for all the 102 grams that it weighs, but I know some people mark it as a strike against this pro...

Great purchase. I really like the rubberized texture. The two buttons on the left are very well positioned. The ones on the right require some adjustment of my hand position, but nothing major.

I switched from a Razer Death Adder, to the Steelseries Sensei. After a few hours of playing around with the Sensei, i think its safe to say that the Sensei feels way better than the Death Adder.

Very Smooth feeling; Glides really easily; Very nice side buttons

Haven't found any at the moment

Probably the best gaming mouse I've ever used. Although it is not as comfortable as the Razer DeathAdder due to its ambidextrous design, it definitely has a nicer feel to it. This mouse is definitely worth the price, but if you aren't that serious about gaming, there are cheaper mice out there.

Comfortable -Steel Series Engine easy to use -Tons of customization settings -Looks great

-Thumb buttons on both sides; I don't mind the thumb buttons on the left side (I'm right handed) and I understand the mouse is ambidextrous, but the buttons on the right side drive me nuts -Costly

Great mouse to go with gaming. 8 Clicks on it is very convenient in game and out. The mouse is very easy to move when in game. Colour lighting is really cool.

Like this the title, this mouse is simply fantastic. It has all the settings I need, and more.

This mouse is a great mouse with great features designed to make gaming easier! The programmable buttons make playing games like LoL and Dota 2 easy as pie! Nice and comfy too!

Nothing special to write about the mouse. All stuffs about it can be found in the steel series website. Its truly the "sensei". Extremely top notch, all buttons and other features can be customized through steel series engine, the software you need to download from steel series website for added...

Really nice mouse, more features than what you need for general FPS. If you can use and get used to..

From the rather simple and stylish box the SteelSeries Sensei Wireless has been quite a surprise. The contents are nicely packaged and although the Sensei feels very lightweight and small, it's very well built.
